4 1. Interpretation 1.1 Definitions Access Arrangement means the current access arrangement approved in respect of the network under the Code. Access Code means the Electricity Networks Access Code Act means the Electricity Industry Act Application means an access application made under the applications and queuing policy. Capital Contributions Policy means the capital contributions policy in the access arrangement. CBD means the area in the Perth CBD in which sites are supplied from the Hay St, Milligan St, Forrest Ave, Wellington St and Cook St substations. Care and Maintenance means a temporary period of reduction in consumption at a customer s site for maintenance purposes. CMD, or Contract Maximum Demand, for a contracted point, means the maximum rate at which a user is permitted to transfer electricity out of the network at the contracted point, being either: (a) (b) the amount specified in the user s access contract from time to time; or if no amount is specified the user s access contract, the maximum rate of electricity permitted to be transferred though the connection assets under the technical rules. Contestable in relation to a customer, means a customer whose load exceeds the threshold of contestability as prescribed under Section 93 of the Electricity Corporations Act 1994 or another enactment. Contracted Point means a point on the network identified in an access contract as either an exit point or an entry point. Contribution means any contribution made under the capital contributions policy. Customer has the meaning given to it in section 3 of the Act. Customer Transfer Code means the Electricity Industry Customer Transfer Code 2004, made under section 39(2a) of the Act in respect of the matter referred to in section 39(2)(b) of the Act, and includes all rules, policies or other subordinate documents developed under the Customer Transfer Code. Customer Transfer Request means the transaction defined in the Customer Transfer Code. Default Retailer in respect of an exit point at the time a customer moves out means the retailer with the customer s exit point listed in their access contract at the time the customer moved out. DSOC or declared sent out capacity, for a contracted point, means the maximum permitted rate at which a user is permitted to transfer electricity into the network at the contracted point, being either: (a) the amount specified in the user s access contract from time to time; or 4

5 (b) if no amount is specified the user s access contract, the maximum rate of electricity permitted to be transferred through the connection assets under the technical rules. LV Connection means a contracted point connected to the network at a voltage of 415 V. Meter means a physical measuring device that measures either the consumption or generation of electricity at a Contracted Point (demand and/or half hourly interval). Meter Point means the point at which a meter is installed to measure the consumption or generation of electricity. Meter Set is the point where multiple meters are summated (including the summator meter). Metering Code means the Electricity Industry Metering Code MV Connection means a contracted point connected to the network at a voltage between 6.6 kv and 33 kv. Network means those parts of the SWIS that are owned, operated or owned and operated by the Western Power Networks business in respect of which an application is made under this applications and queuing policy.

Price list means the price list in the access arrangement. Retailer has the meaning given to it in the Customer Transfer Code. Site means a single lot, as defined by the Department of Land Information. Transmission HV Connection means a contracted point connected to the network at a voltage of 66 kv or above. UMI or Unique Market Identifier means the unique identifier assigned to the meter at a contracted point. 1.2 Access Code definitions apply Unless the contrary intention is apparent, a term with a defined meaning in the Access Code has the same meaning in this price application policy. 1.3 Interpretation Unless the contrary intention is apparent: (i) a rule of interpretation in the Access Code; and 5

6 (ii) the Interpretation Act 1984, apply to the interpretation of this price application policy. 2. National Market Identifiers (NMIs) 2.1 NMI allocations NMIs are allocated to each entry and exit point as per the document entitled NMI Allocation Procedure for the Western Australia Electricity Market. 3. Network Tariff Nominations 3.1 Suitability of meter types for network tariff nominations A customer s meter needs to support the nominated network tariff. For example, the Time of Use network tariff cannot be supported by a meter that can only aggregate consumption and therefore cannot be nominated for a customer with this type of meter installation. 3.2 Transmission exit points (less than 66 kv) The distribution component of a network tariff (including the administration charge) does not apply to transmission exit points connected to the network at a voltage of less than 66 kv (for example, customers directly connected to a zone substation). This applies to both the standard and transition network tariffs. Metering charges will be applied. 3.3 Migration from transitional tariffs An exit point that has moved from the transitional tariff to a nominated standard tariff cannot revert back to the transitional tariff. Transitional tariffs are only available to customers who were contestable before 1 July Network tariff consumption ceilings Where a Metered Demand network tariff has been nominated and the maximum demand has exceeded 1500 kva in three or more billing periods over a 12-month period, the retailer must make an application under the applications and queuing policy to migrate the exit point to a CMD network tariff There is currently no consumption ceiling for the Time of Use Energy Large and Anytime Energy Large network tariffs. 3.5 Application of rolling peak demand for customers on Metered Demand network tariff The rolling peak demand for customers on a Metered Demand network tariff, who are the subject of a customer transfer request, will be continuous, not reset, on the date of the transfer between retailers. 3.6 Tariff nominations for customers on care and maintenance Existing CMD network tariff customers who have gone to care and maintenance are eligible to go to a lower value network tariff and booking, but must accept the possibility of losing the unbooked network capacity to other customers. 6

7 3.7 Notice period for tariff nomination changes Where there is no change in a customer s load, 20 business days written notice is required to nominate a change in network tariff for that customer to allow for administration and billing changes. Networks will provide receipt of written notice within 2 working days and then a decision on nomination at the end of a further 18 working days. Any tariff change will take effect in the billing period subsequent to the date of application or at a later date as agreed. 3.8 Frequency of tariff nomination changes A change in network tariff can be made only once every financial year. The retailer shall ensure that the nominated network tariff is best suited to their customer. 4. Network Tariff Nomination for a New Connection A network tariff nomination for a new connection must be made as a part of the application submitted by the retailer. If no network tariff has been nominated for the new connection: (a) (b) in the case of a new or existing customer at a new premise, the meter will only be installed and connection finalised after a network tariff nomination is made; or in the case of a new customer at an existing premise or an existing customer moving to a different existing premise, the network tariff will default to Anytime Energy up to the beginning of the billing period in which the network nomination is made. 5. Access Charges for Exit Points Between Customer Occupancies With the exception of the CMD network tariff, the fixed charge of a network tariff applies during the vacancy period of an exit point, between customer occupancies. This is applicable to the default retailer until the next new connection for that exit point, where: (a) (b) the exit point remains on the default retailer s access contract and the full, nominated network tariff applies from the date of the new connection; or the exit point is transferred to another retailer via a customer transfer request, and is deleted from the default retailer s access contract. Where a CMD network tariff is applicable to an exit point before a customer moves out, the exit point is removed from the default retailer s access contract, and no further access charges will be applied. The standard rules of CMD nomination apply in these cases. 6. Contract maximum demand and declared sent out capacity nominations 6.1 Confirm sufficient network capacity 7

8 Where a customer is seeking to increase their CMD, the retailer must confirm with Networks via an application that sufficient network capacity is available or augmentation is completed before a request for an increase in CMD nomination is accepted. 6.2 Notice Period for Changes in CMD or DSOC For changes in CMD, written notice to Networks is required at least 30 business days before the effective date of the CMD increase or decrease. If further time is required for processing a CMD increase requiring network augmentation, Networks will provide information regarding the length of processing time. Written notice is required 30 business days for changes in DSOC. The 30 business days cater for the possible need to undertake planning studies to assess the change in DSOC. Again, if further time is required for process a DSOC increase requiring network augmentation, Networks will provide information regarding the length of processing time. 6.3 Frequency of changes in CMD or DSOC Only one change in CMD or DSOC can be made each financial year per customer. Networks may agree, at its discretion, to a change in CMD or DSOC made more than once each financial year in special circumstances, excluding seasonal variations. In the case where the CMD is reduced, if another customer wants to immediately use the spare network capacity, then the customer with the reduced CMD shall be given 1st option to make a booking for that firm network capacity via their retailer. 6.4 Capacity to supply CMD or DSOC Where the retailer requests a CMD on a customer s behalf, and that CMD exceeds the capacity of the feeder supplying this customer, the contribution for the system upgrades to meet the CMD will be assessed on an individual case by case basis in accordance with the capital contributions policy. Likewise, where the retailer requests a DSOC, and that DSOC exceeds the capacity of the network, the cost of system upgrades to meet the DSOC will be assessed on an individual case by case basis in accordance with the capital contributions policy. 7. Excess Demand Charges Excess Network Usage Charges will be applied to retailers for those customers who exceed their nominated CMD or DSOC. In general, a customer s maximum demand should not frequently exceed the nominated CMD or DSOC over more than three months. If this is the case, then the retailer and/or customer shall take all reasonable measures to nominate a new CMD appropriate for the long-term increase in the customer s maximum demand. 8. Loss Factors Loss factors applicable to various network tariffs are described in price list. 8

9 9. Contributions 9.1 Contributions general Contributions will be calculated in accordance with the Capital Contribution Policy. 9.2 Obligations of the customer Where a customer has paid a contribution for a future load increase, they must nominate and continue to pay for a corresponding CMD at the same time. Otherwise, the customer accepts the possibility of the additional network capacity being used by other customers. 9.3 Capital contribution credits Pre 1 July 2001 contestable customers who made a contribution towards the cost of network augmentation (prior to 1 July 2001) may be eligible for a credit against their network access charges. Either the customer or the retailer can make enquiries regarding possible capital contribution credits. 10. Backup Capacity 10.1 Definition and application of Firm Backup Capacity Firm Backup Capacity ("FBC") is defined as capacity that is reserved for a particular customer and is accessible by that customer at all times, either automatically or by manual switching. FBC is nominated by a customer via its retailer and is reserved for that particular customer for as long as the customer is willing to continue to pay for the capacity Treatment of Firm Backup Capacity from the same substation as normal supply. The supply that provides the FBC is treated as a different supply point to the normal supply feeder. However, multiple sets of distribution charges apply since, in this case, only distribution assets are being utilised for backup. No additional transmission related charges apply. (a) (b) (c) (d) (e) (f) (g) The normal supply and the backup supply must be separately metered. Only a CMD tariff can be applied to the backup supply, however any tariff can be applied to the normal supply. Separate metering charges will apply to each meter point. Excess Network Usage is also applied separately to the normal supply and the backup supply. The Demand Length is calculated for the FBC feeder supply. No administration charges apply to the FBC. LV and HV connections are treated the same Treatment of Firm Backup Capacity from different substation as the normal supply Same rules as above, however Transmission charges apply and the prices for each particular substation will also be applied Treatment of Firm Backup Capacity where normal supply is from a generator 9

10 Same rules as 9.2, however Transmission charges apply and the prices for the backup supply substation will also be applied. 11. Application of Discount on Transmission Common Service Charge For Transmission or Transition Network Tariffs, a 75% discount on the transmission common service charge applies when the backup supply is used with a load factor of 15% or less (load factor assessed over a 12 month period). For a bundled Transmission Network Tariff, a 25% discount is applied to the total transmission charge. 12. Multiple Points of Supply 12.1 Multiple points of supply from the same substation If the customer s load is below 3 MVA the multiple points of supply are treated as a single point of supply for purposes of account billing. These customers are only eligible for CMD network tariffs. For customers with CMD greater than or equal to 3 MVA the load is divided equally over the number of points of supply. Meter charges apply to each meter set (excludes check and summator meters), and demand length charges are calculated per feeder using the distance applicable to the feeder. LV fixed and variable charges apply to all points. However, Excess Network Usage applies to the net demand (CMD) and to transmission use of system and distribution use of system charges for the whole site. Also, only one administration charge is applied to the site. HV and LV connections are treated the same. Note: Due to the network operating conditions of the CBD, CBD customers with multiple points of supply shall be treated as if they have a single point of supply Multiple points of supply from different substations Same rules as above, however prices for each particular substation will apply. 13. Metering 13.1 Meter requirements Contestable customers moving off a gazetted Western Power Retail tariff to supply from another retailer are currently required to have electronic meters with half hourly load data recording capability for energy settlement purposes. If an existing meter does not comply with this requirement, then the cost of upgrading the meter, including remote communication equipment, will be charged to the retailer Additional meter reading charges Additional individual meter read charges will be applied where the estimated meter read costs exceed the amount allocated in the monthly account service fee Metering Code 10

11 All other metering provisions are contained in the Metering Code. 14. Retailer Access to Customer Metering and Standing Data Information The request for historical consumption data and/or the request for standing data forms are available on Western Power s web page. Retailers must complete the form and submit to Networks for individual customer half hourly metering and standing data. The data will be provided as per the Customer Transfer Code. 11
